Lightning does strike twice for Bolt as brilliant Jamaican claims sprint double... and Gemili narrowly misses out on medal

Usain Bolt won his seventh World Championship gold medal as he coasted to victory in the 200 metres at the Luzhniki Stadium on Saturday night.

The Jamaican, also a six-time Olympic champion, added 200m gold to the 100m title he won last Sunday, dominating the field to win in 19.66secs, the fastest time in the world this year.

Bolt's compatriot Warren Weir, 23, was second in 19.79secs, a personal best, with American Curtis Mitchell, 24, taking the bronze with a late surge in 20.04secs.

Sealed with a kiss: Usain Bolt followed up his triumph in the 100 metres by blazing to glory on Saturday

British teenager Adam Gemili, 19,
finished fifth in the first senior global final, missing out on a medal
by just four hundredths of a second.

His
time, 20.08secs, did not quite match the extraordinary performances of
Friday, when Gemili twice broke his personal best and became the second
British man to dip under 20 seconds, but the teenager's display
announced him as a genuine contender on the global stage.

Gemili said: 'I was very close to a medal - just four hundredths and I
missed out on the Olympic final (in London last summer) by four
hundredths as well, so it's always those fours.

'But
as I get older and stronger that will hopefully come down and down and
down. Hopefully I'll be up there getting a medal in future years.'

He's done it again: Bolt is mobbed by photographers after claiming his second medal of the championships, and he's now won a third

Bolt,
26, was in the lane inside Gemili and had made the uncharacteristic
gesture of shaking each of his competitors' hands on the start line, but
the British athlete was not fazed.

He
just smiled, as usual, when the camera panned onto him and kept his
cool when Bolt passed him and came out of the turn ahead before
extending his lead down the home straight.

Bolt ran 19.99secs in Crystal Palace just before his 19th birthday;
Gemili has now clocked 19.98secs after just 18 months of serious,
full-time training.

The
Jamaican also finished eighth in his first World Championship final in
Helsinki in 1995, struggling to finish after suffering an injury, while
Gemili has already achieved a highly creditable fifth place.

Nobody is saying Gemili will be better than Bolt, but the signs are
certainly encouraging for a British teenager who apparently has the
world at his feet.

Gemili said: 'It's an unbelievable experience to be in that final on
the outside Usain Bolt and just being in the top eight and finishing
fifth. I'm just very proud, very happy and very grateful to be in this
position. 'It was just after Bolt and the whole stadium erupted and I
thought: "One day hopefully I'll be in that position." It put a smile
on my face and helped me stay relaxed for my race.'

Bolt's dominance shows no sign of abating and another victory in the 4x100m relay on Sunday will see him equal American legend Carl Lewis' record of eight world gold medals.

'I haven't really thought about that,' he said. 'I've done a lot throughout the years. 'My main goal was to make myself a legend and I solidified that at London last year.

'I'm not really worried about winning medals and counting them. 'My next big goal is to go to the Olympics and do something that has never been done before - winning the 100m and 200m.'
